To all lwhom t may concern: f

Be it known that L-THOMAS BREHENY, of Melbourne, in the State ofVictoria, Commonwealth of Australia, have invented certain new anduseful improvements in Condensing Apparatus, of which the following is aspecification.

This invention relates to an apparatus for preserving the volatile hopessences or aromas coming from the copper or boiler in which the wort isboiled with the hops in order to improve the quality of the beer andlike brews. l

The method and apparatus comprised in the present invention consists inarranging a specially constructed condenser in oommunication with theltop of a copper whereby the .vapor arising from the heated contents ofthe latter will pass to and be condensed in the former.

rlFhe condensed vapor or steam is delivered to a supplementary cooling.coil and thence to a mixing chamber where it is brought into contactwith the non-condensable or practically non-condensable odoriferousgasesfor fumes which pass from the upper end of the condenser and arecollected and delivered to the said chamber in a convenient' way.

The liquid resulting from the condensationot the steam or vapor given`oit from the copper absorbs the aroma of the odoriferous gasesy orfumes in the mixing chamber and as a result is richer in flavor andaroma than the original liquid contents of the said copper. The liquidis conveyed. from the mixing chamberto an open vessel or chamber fromwhich it is delivered to a ferment ing vat.

The invention is exceedingly simple, reliable and comparativelyeconomical to install and keep running and every provision is made forcleansing the apparatus when required. f

understood reference will nowbe had to the. accompanying sheets otexplanatory drawings wherein Figure 1 is a view in elevation of the ap-vparatus comprised inthe present invention the various parts beingarranged to show their approximate relative positions. Frg. 2 is a viewin sectional elevation of a condenser forming part of the apparatus.Fig.

- which has its lower end connectedl to the center of the top of acopper 2 and its upper end arranged in communication with a circuitouspassage 3 or circuitous passages formed between two concentricallydisposed annular water jackets 4 and 5 forming a condenser of any wellknown type and construction.

The outer water jacket 5 is strengthened by bands 51 or in any otherpreferred way.v The water jackets 4 and 5 are kept at as uniform adegree of coldness as possible by passing cold water continuouslytherethrough from branch pipes 8 and 9 respectively connected to a mainsupply pipe 10. The water passes through the jackets 4 and 5 and isheated moreor less therein and then passes to discharge pipes 11 and 12connected to the'lower ends of the said jackets.

j The delivery end of the discharge pipes 11 and 12 preferably open intoa sump 13 or the like which is connected by a pipe 14 to a liquor or hotwater vat 15 arranged above the copper 2 in the ordinary way. The mainwater supply pipe 10 and the branch pipe 8 are carried vertically upwardbeyond and lare then given bends 16 which will cause their open ends tolie within the sump 13. The main supply pipe 10 and the branch pipe 8are fitted with cocks 101 and 81wl1icl1 can be regulated to permit justsufficient flow to accommodate the pipes 8 f and 9.- The Water isdelivered to the pipe In order that the invention may bereadily-10`under pressure and vnormally rises above the junction of the pipes 8and 9 and should the pressure increase in the pipe above the cock101,*the water will flow out the end of the said pipe into the sump 13and thereby automatically keep the pressure and consequently the tlow inthe said pipes 8 andf9 approximately uniform.

he upper end of the outer water j acket 5 is covered by a cap or hood 17from the center of which a pipe 18 projects vertically. This pipe 18 isbent downwardly and upwardly and its upper end is provided with CTI arelief valye 19 of approved form. The second bend in the pipe normallycontains water to 'form a seal to prevent the escape ofthenon-condensable gases passing through the condenser fromv the copper.Normally, the water in the pipe 18 prevents v 4the escape of steam orvapor but should the Arises to a pressure within the condenser becomeeX- cessive thevwater will be forced upwardly thereby raising the valve19 and permitting the water and sufficient steam to escape to relievethe said pressure. If preferred, the pipe 18 can b dispensed with and arelief valve similar to 19 can be fitted to the cap or hood 17 in anapproved way.

The non-condensable gases which are rich in aroma pass together with anyvapor not condensed in the passage 3 along a pipe 20 leading from the.cap or hood 17 covering the upper end of the condenser, to the mixingchamber 21 into which the condensed vapor or steam alsois delivered. Theliquid resulting from the condensation of the vapor or steam in thecondenser trickles back through the passage 3 therein and along the flue1 to a point where it 'is trapped by a ring partition 22 or the like insaid luel The trapped liquid passes into a pipe 23 leading to thevupperend of a cooling coil 24 locatedin af water tank 25 disposed inany convenient position.

The cooling coil is formed of a flat pipe or tube as shown in Fig. 7 andits lower end is connected to a pipe 26 leading to the mixing chamber 21hereinbefore mentioned. The mixing'c ber 21 is divided into twocompartments 27 and 28 and into the upper compartment 27 is deliveredthe condensed steam or vapor and into the lower compartment 28 isdelivered the vapor and (or) gases not condensed in the condenser.

The partition 29 dividing the mixin chamber 21 into the two compartments2l and 28 is perforated and the liquid delivered to the top compartmentpasses to the lower compartment in a fine spray. The end of the pipe 20ldelivering the noncondensable gases into the lower compartment 28 ofthe mixing chamber 21 is provided with a spray 30 for-distributing orspreading the said gases evenly to insure -them intermingling with theWhole of and the aroma of the same being absorbed by the liquid showeredfrom the upper compartment 27.

lAn overflow pipe 211 is located on the side of the mixing chamber 21toA permit of the liquid'delivered to the upper compartment passing tothel lower compartment Vwhen it predetermined height therein.

' 'The top of the mixing chamber is provided with a hinged or detachablecover 271 and glasses272 can be arranged in any preferred way that-Willpermit of a ready inspection fof the upper compartment 27. The liquidabling them to be delivered to the lower compartment 28 of the mixingchamber 2l passes therefrom through a pipe 31 leading to a perforatedpipe 32 located in or near the bottom of an open vat or chamber 33disposed in any convenient position.

Should any ofthe aroma of the noncondensable gases not be absorbed bythe liquid in the mixing chamber 21 the absorption will take place inthe open chamber 33. The liquid delivered to the open chamber 33 isallowed to pass through a pipe 34 to a fermenting vat or the like (notshown). The copper 2 is'provided with a relief pipe fitted with acontrolling cock 36 and the upper ends'of the water jackets 4 and 5 areprovided with air outlet pipes 37 and 38 which preferably communicatewith the main water supply pipe 10. The air pipes 37 and 38 connected tothe upper ends of the water jackets 4 and 5 permit of the escape of airwhen water is being delivered thereto prior to the commencement ofoperations. The object of the relief pipe 35 is to permit of theintroduction of air to the copper 2 at the completion of operations tobreak down the vacuum caused by thc condensation of steam therein andthereby permit of the top 39 of the said copper being easily opened.

A pipe 40 connects the lower part of the water tank 25 to the supplypipe 10 and a continual circulation of cold water is maintained in thesaid tank to Acool the coil 24 and as the water in the Vtank becomesheated it passes therefrom through a pipe 41 which delivers into thesump 13 arranged in communication with the liquor vat 15. Provision suchas test pipes 42 and 43 is made for readily determining the temperatureof the water in the water jackets and for enkept at as uniform atemperature as possible and provision such as priming pipes 44 is madealso for insuring the liquid and vapor passing freely through all thepipes of the apparatus. The pipes 42 and 43 can be connected directly tothe Jackets 4 and 5 or to the discharge pipes 11 and 12 leadingtherefrom. These pipes 42 and 43 are provided with taps 421 and 431which when turned on permit of water from the jackets being delivered toa sump 4311 for testing purposes. Should the water in the jackets befound to be of uneven temperature the cocks 101 or 1011 can be operatedto cause a greater or lesser flow of water to their respective jacketsand thereby effect a uniform cooling.

The various parts of the a provided with connections or pipes 45 whichpermit of the attachment of a hose or pipe for delivering steam theretofor cleansing purposes.

It will be readily understood that the condenser, cooling coil, mixingchamber and pparatus arel marianna steam which is delivered theretothrough pipes iti fitted with cocks il', and iG and ii" respectively.

Under normal working conditions the apparatus prevents the escape ofvapor or odoriferous gases to the atmosphere and conveys the same in aliquid state to the fermenting vat to improve and enrich the brew. 'lheuse of the apparatus results Iin effecting considerable economy in themanufacture of beer and similar beverages as it prevents waste andrequires much less fuel than is used with the ordinary brewing plant.
